Hybridization method for fixing fast-growing character of salix matsudana

The invention discloses a hybridization method for fixing the fast-growing character of salix matsudana. The method includes the steps that the salix matsudana is selected as a female parent, and a weeping willow serves as a male parent; female flower branches and male flower branches are subjected to greenhouse water planting; when a large quantity of female flower stigmas secrete transparent mucus, pollination is continuously carried out for 3-6 days, the greenhouse temperature is controlled to be 20-23 DEG C after pollination, the humidity is 60-80%, and it is ensured that pollinated hybrids can development normally; hybrid seedlings are cultivated, wherein the hybrids are collected after being ripe 20-30 days after pollination, then germination acceleration is carried out on the collected hybrids, the hybrids are sown in nutrient cups after sprouting for seedling raising, and timely watering and disease and pest control are carried out. The method is easy to operate, easy to acceptand master, low in cost
